LIQUID-CONTROLLED VALVE.

SPECIFICATION forming part of Letters Patent N o. 686,846, datedNovember 19, 1901.

Application filed June 19, 1901.

To all whom it may concern:

Be it known that I, SAMUEL FOETEP., a citizen of the United States,residing at Bellevue, in the county of Alleghenyand State ofPennsylvania,have invented or discovered new and useful Improvements inLiquid-Controlled Valves, of which the following is aV specication.

In the accompanying drawings,which make part of this specification,Figure I is a side elevation of a liquid-controlled valve. Fig. II is aplan view, partly in section, on line 2 2 of Fig. III. Fig. III is avertical longitudinal section on line 3 3 of Fig. II. Fig. IV is avertical cross-section on line 44 of Fig. III. Fig. V is a verticallongitudinal section showing the main gas-inlet through the bottominstead of the side or top of the valve. Figs. VI and VII are sectionalviews similar to Fig. III.

The object of myinvention generally stated, is to provide means wherebythe iiow of gas or air through what is technically termed thereverse-valve of a regenerative or other furnace can be controlled atthe will of the operator without the use of internal operativemechanism. My mechanism is also adapted to other uses of analogouscharacter or may be used as a cutoi valve.

A further object is to provide means for preventing an accumulation ofbyproductssuch as tar, soot, &c.-in the sealing-chambers, which arewashed out on each reversal of the valve. I also provide simple andefticient means whereby the valve-ports are absolutelyT closed duringthe reversing of the gas or air currents through the valve,andconsequently there can be no waste of gas escaping up the chimneyiiue,asfrequently occurs with other formsof reversing-valves.

Another object of my invention is to facilitate the reversing of valvesof large dimensions by obviating the necessity of moving heavy parts ofthe valve during its reversal.

It will be seen from Fig. I that it requires very little power toreverse my valve, even of the largest size, as no parts of considerableweight need to be moved, the reversing being effected by simply openingand closing alternately the small auxiliary overflow-valves 18, 19, 20,and 21.

In the accom panyingdrawlngs, 'l represents Serial No. 65,162. v(Nomodel.)

a valve-casing having a gas or air inlet 2 and a valve-hood or valveproper, 3, provided with anges 4, 5, 6, and 7. These flanges projectdownwardly a short distance below the top of the bed-plate or valve-seat8. Valve-casing 1 is supported upon the top of bed-plate 8 by means ofthe flanges 4, 5, 6, and 7, which are cut away, as indicated at 9'9 inFig. IV, affording a means whereby the sides and ends of the casin g 1remain suspended in the trough 10. In the bed-plate 8 are shown verticalpassages 11, 12, and 13. The walls of these passages, in conjunctionwith the sides and ends of the bed-plate 8, form the compartments 14,15, 16, and 17. Auxiliary valves 18, 19, 20, and 21 are secured to theexits 22, 23, 24, and 25 of said compartments. Connected to auX- iliaryvalves 18, 19, 20, and 21 are valve-levers 26, 27, 28, and 29. Theselevers are operative through the fulcrums 30, 31, 32, and 33,transversely-moving bar 34, shoulders 35, 36, 37, and 38, and` levers 3939.

40, 41, 42, and 43 represent slots cut into the sides and ends of thebed-plate 1. 44 is the water-supply pipe.

In the operation of my invention by assuming lever or levers 39 to be ina vertical position or moved over to point A, as indicated in Fig. I,the auxiliary valves 18, 19, 20, and 21 would be closed. Water wouldthen be permitted to flow through pipe 44 into trough 10, filling thetrough, so that it would iiow over the slotted portions 40, 41, 42, and43 of the upper edges of the ends and sides of the bed-plate 8 and intothe compartments 14, 15, 16, andP 17 of the bed-plate 8 until it risesin said compartments to a level with the flow from the trough 10. (SeeFig. VI.) At that `level the passages 11, 12, and 13 are cut off fromcommunicating with each other through the valve by the lower ends of theiianges 4, 5, 6, and 7, being below the water-line in said compartments.When the water reaches to a level in the compartments and the trough, itcan continue to rise until it overflows the outside of the trough 10.This I provide for by making the outer ange of the trough 10 on a lowerhorizontal plane than the top edge of the sides of the bedplate 3. Theadvantage of this construction is that it will be impossible for thewater to ICO . sage 12.

enter the vertical passages 1l, 12, and 13.- Assuming the compartmentsto be filled with water, as above described, the next operation would beto emptyeither of the sets of alternative compartments, so that apassage would be opened to the flue or vertical pas- This isaccomplished as indicated in Figs. I and III, wherein when the lever 39is pushed over to the position as shown in Fig. I from the positionmarked A, same figure, the shoulders 35 and 37 will bear against theends of valve-levers 26 and 28, causing, through fulcrums 30 and 32, thesaid valvelevers to rise from the valve-seats and permitting the watercontained in compartments 14 and 16 to escape through the exits 22 and24 and out through the auxiliary valves 18 and 20, emptying thecompartments to the vwater-line indicated in Fig. IV, wherein 45represents a downwardly-projecting flange, which acts as a seal toprevent the escape lof gas through the auxiliary valves 18, 19, 20, and2l. Compartments 14 and 16 being unsealed, the gas or air passes throughinlet 2 and between the casing 1 and central hood 3 into compartment 14around flange 4, out of compartment 14 and into vertical passage 11, andout to the furnace. The waste gases pass up vertical passage 13, downinto compartment 16, under flange 6, up and out of said compartment anddown the central 4passage or flue 12, and out through the stack.

When it becomes necessary to reverse the direction of the currents ofgas or air through the valve, the operation is as follows: Lever 39 ispushed to position indicated by A, Fig. I, and held in that position fora few seconds. Lever 39 has moved bar 34 forward, and the shoulders 35and 36 of bar 34, against which bear the upper ends of valve-levers 35and 3,7, will then move to the right, allowing the valve-levers 26 and28 to rotate around their fulcrums 30 and -32 and to close the seats ofthe auxiliary valves 18 and 20, thereby permitting the compartments 14and 16 to till up with water until they are sealed from each other orwith the gas or air inlet or vertical passages in the valve, thuspreventing any danger of back {iashes or the escape of gas to thechimney-flue.

The operator, when the compartments 14 and 16 are filled with liquid,(Which-takes but a short period of time,) pushes the upper end of lever39 over until it reaches the position indicated at B in Fig. I. Duringthe operation the lever is drawing bar 34 toward the gas-inlet end ofthe valve. Shoulders 36 and 38 are brought into contact with the up perends of valve-levers 27 and 29, raising said levers upon their fulcrums3l and 33, unsealing the seats of auxiliary valves 19 and 21, andemptying the compartments 15 and 17 to the approximate level of theauxil- When the valve compartments are in the above described condition,(see Fig. VIL) the gas or air from inlet 2 will pass down and betweenthe end Walls of the casing l and the side of iange 7 into compartment17 and around flange 7down and out of vertical passage 13 to thefurnace. The waste gases will pass up vertical passage 11, turn downinto compartment 15 and around iiange 5, up and out of said compartment,and down iiue 12 and out of the stack.

At each reversal of the valve by admitting a tiushing flow of water thesealing-chamber may be thoroughly washed out, thus preventingaccumulations which, if allowed to collect, might seriously interferewith the successful operation of the mechanism.

In Fig. V the main gas -inlet is shown through the bottom et the valve;otherwise the operation and construction are similar to those alreadydescribed, except that the water iiows into chamber 14 on the side only.

It will be seen by the general arrangement, as shown and described, thatthe gaseous currents are easily controlled and directed alternately bymeans of operating the lever,which when pushed to either of the threepositions indicated changes the relative courses of the gas or preventsit from passing through the valve.

Having described my invention, I claim- 1.
